2021’s Dune did a great job of adapting a dense science fiction novel, but it only gave us half the story. That’s where Dune, Part Two comes in. This highly anticipated sequel covers the second half of Frank Herbert’s original novel, and it introduces a lot of new characters in the process.

Who are these new faces in the Dune-verse? How do they shake up an already complex storyline? Why exactly is Paul riding a Sandworm? Here’s what you need to know about Dune, Part Two after watching the first trailer.

Dune: Part Two stars Timothée Chalamet, Zendaya, Rebecca Ferguson, Josh Brolin, Dave Bautista, Stephen McKinley Henderson, Stellan Skarsgård, Charlotte Rampling, Javier Bardem, Austin Butler, Florence Pugh, Christopher Walken and Léa Seydoux. The film hits theaters on November 3, 2023.
